Preheat the air fryer to 360 degrees F.

In a large shallow bowl, whisk together the buttermilk and eggs until well combined. 

In a second shallow bowl, add the flour, paprika, garlic powder, onion powder, salt, and pepper and whisk well.

Using tongs or your hands, dip each piece of the chicken in the flour,
shaking off any excess. Next, dip it in the buttermilk, then roll it in
the flour, covering it completely. Set on a baking sheet and set aside.
Repeat with the remaining chicken. 

Spray all sides of the chicken pieces with oil spray.

Place 4-5 pieces of chicken in the bottom of the air fryer basket, or as many that fit in your air fryer basket or oven in a single layer. 

Cook for 15-20 minutes. Carefully flip the chicken and cook for another 5-10 minutes until 165 degrees internally.
